Just inside the library, there were 2 Lego lions, which were really cool and almost as popular as their outside counterparts.
Up on the third floor is the Rose Main Reading Room. There is a quiet side and a regular side, both have computers and wifi access. The beautiful, huge rooms really took my breath away. The chandeliers look very familiar, and remind me of the ones hanging in Grand Central Terminal.
There are a few more pictures at Unseen NYC's Facebook page.
